+Reading sectors from floppy with BIOS INT 13h is broken
+
+I'm developing a game bootable from a floppy disk, written in i386 assembly. I found out it doesn't work on newer QEMU versions. I managed to isolate the issue and it seems that there's a problem with handling of BIOS interrupt 13h when it comes to reading disk sectors (AH=02).
+
+I've written a simple test in assembly. It simply accesses four different floppy disk sectors and prints out the strings they contain. The problem is, the two latter strings don't show up at all nor the BIOS interrupt returns an error (CF set). I've attached the code to this bug report. I use following commands to compile it and run:
+
+$ nasm disk-test.asm -o disk-test.bin
+$ qemu-system-i386 -boot a -fda disk-test.bin
+
+After running, the expected output is:
+
+    I am a test string from boot sector
+    C:H:S 0:0:2 - Hello
+    C:H:S 0:0:3 - there!
+    C:H:S 0:1:4 - In QEMU you can't
+    C:H:S 1:0:5 - see these two lines! :(
+
+while the actual output is:
+
+    I am a test string from boot sector
+    C:H:S 0:0:2 - Hello
+    C:H:S 0:0:3 - there!
+
+
+So far, I found this problem in the current QEMU version for Ubuntu 18.04 (Debian 1:2.11+dfsg-1ubuntu7.8), as well as in the 3.1.0-rc3 and 2.12.1 versions, available on the www.qemu.org website. Thus, the issue doesn't seem to be very recent.
+
+To be sure, I ran the program on my other machine with older QEMU version (Debian 2.0.0+dfsg-2ubuntu1.43) and on my RaspberryPi 2 (Debian 1.1.2+dfsg-6+deb7u25) and everything works as expected there. It also works well in VirtualBox.
+
+I hope these information are useful to you, however, I feel like this bug may be more related to Seabios. If so, please let me know and I will report it somewhere else.
